Patrick Bellasi 658005a178 cgroups: properly format attributes path and check for being supported
CGroups controller can be mounted by specifying a "noprefix" option,
in which case attribute names are named as:
   <mountpoint>/<attribute_name>
instead of the (more recent) naming schema using:
   <mountpoint>/<contoller_name>.<attribute_name>

For example, Android uses the old format for backward compatibility
with user-space. Thus, it's possible in general to work on a target
system where some controller are mounted "noprefix" while others not.

This patchset adds a set of updates which allows to use the proper
attributes naming schema based on how the controller has been mounted.

This patch makes use of the Controller::_noprefix option to properly
build the attribute path. It adds also a check which reports a more
clear error in case an attribute is set which is not provided by the
controller.
